While the man with the gun empties the cash register, the other man goes behind the counter and starts grabbing boxes of cigarettes.

Police said they fled with $435 and several boxes of Marlboro cigarettes.

"This is hard. We work hard for our money. The boss works hard for his money. For somebody to come in here and do this, it just isn't right," said manager Randy Shoup.

The man in the black sweatshirt was described as white, in his 20s, about 5 feet 4 inches to 5 feet 5 inches tall and 140 pounds. He also wore a dark bandana over his face, white gloves, dark jeans and black shoes.

The second man was described as possibly being in his 20s or 30s, 6 feet to 6 feet 2 inches tall and weighing 230 pounds. He wore a black baseball cap, a white bandana over his face, black leather gloves, blue jeans and a gray button-down dress shirt.

"With all these video cameras, we're gonna catch them. It's just a matter of time," said Shoup.

Anyone with information should contact state police at the Indiana barracks at 724-357-1960.
